Using work energy theorem, W g =Δ K . E (10)( g )(5)=(1/2)(10) v 2-0 v =10 m / s

Q. As shown in the figure, a particle of mass 10 kg is placed at a point A When the particle is slightly displaced to its right, it starts moving and reaches the point B The speed of the particle at B is x m/s (Take $g = 10 m / s^{2})$ The value of 'x' to the nearest integer is _______.

Using work energy theorem,
$W_{g} = Δ K . E$
$(10) (g) (5) = \frac{1}{2} (10) v^{2} - 0$
$v = 10 m / s$
